To know oneself, one should assert oneself.
If you think you can do it, you can.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Know or listen to those who know.
Leap, and the net will appear.
It's always too early to quit.
Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
The secret of getting ahead is getting started.
If you travel first class, you think first class and you are more likely to play first class.
